I'll have to try the KAM trick. So far i haven't had any problems doing the steps the SSM states. The truck has to be over 160 degrees. The one I did that was a cold engine surged bad until I retried everything at operating temp then seemed ok. You can hear the vgt cycling through as the exhaust changes pitch throughout the five minutes. And if you monitor the pids PWRStrokeMaster stated it does work.
